【问题描述】：
我有一个 json 文件，它根据当前年份和上一年为销售人员加载销售数据。
我创建了一个表格，其中显示了每个销售人员每年的总销售额，在最后一行，我需要加载所有销售人员的总销售额。如下图所示：
我正在使用dc.dataTable 创建我的表。
您能否告诉我 DC.js 中是否有任何方法可以在我的表中创建一行来放置总销售额？
这是我的代码，提前谢谢你。
var vendedorTable = dc.dataTable("#Vendedores");
var url = 'http://www.json-generator.com/api/json/get/cgsUhkPSjS?indent=2';
d3.json(url).then(function(data) {
data.forEach(function(d) {
var myCrossfilter = crossfilter(data);
var all = myCrossfilter.groupAll();
dc.dataCount(".dc-data-count")
.dimension(myCrossfilter)
.group(all);
vendedorDim = myCrossfilter.dimension(function(d) {
return d.vendnm;
});
var vendedorGroup = vendedorDim.group().reduce(reduceAdd, reduceRemove, reduceInitial);
function reduceAdd(p, v) {
p.totalAno += +v.Vendas_Ano;
p.totalHomologo += +v.Vendas_Ant;
return p;
}
function reduceRemove(p, v) {
p.totalAno -= v.Vendas_Ano;
p.totalHomologo -= v.Vendas_Ant;
return p;
}
function reduceInitial() {
return {
totalAno: 0,
totalHomologo: 0,
};
}
// formatter = d3.format(".3s");
// formatter2 = d3.format(".0%");
//Fake Dimension
rank = function(p) {
return ""
};
function checkRows(d) {
if (d.value.totalAno <= 0 || isNaN(d.value.totalAno) || d.value.totalHomologo <= 0 || isNaN(d.value.totalHomologo)) {
return 0;
}
return d;
}
//vendedorTable
vendedorTable.width(500)
.height(480)
.dimension(vendedorGroup)
.group(rank)
.columns([function(d) {
d = checkRows(d);
while (d != 0) {
return d.key;
}
},
function(d) {
d = checkRows(d);
while (d != 0) {
return Number(Math.round(d.value.totalAno * 100) / 100).toLocaleString("es-ES", {
minimumFractionDigits: 2
}) + '€';
}
},
function(d) {
d = checkRows(d);
while (d != 0) {
return Number(Math.round(d.value.totalHomologo * 100) / 100).toLocaleString("es-ES", {
minimumFractionDigits: 2
}) + '€';
}
}
])
.sortBy(function(d) {
return d.value.totalAno
})
.order(d3.descending)
vendedorTable.on('pretransition', function(table) {
table.selectAll('td.dc-table-column')
.on('click', function(d) {
let filters = table.filters().slice();
if (filters.indexOf(d.key) === -1)
filters.push(d.key);
else
filters = filters.filter(k => k != d.key);
if (filters.length === 0)
vendedorDim.filter(null);
else
vendedorDim.filterFunction(function(d) {
return filters.indexOf(d) !== -1;
})
table.replaceFilter([filters]);
dc.redrawAll();
